Uni-Torque™ Lock Nut

Locking Nut Key Details

The top thread section of the Uni-Torque Lock Nuts are scientifically displaced at two 180°opposing areas. This displacement or deflection ovalizes the top threads of the nut and deflects these threads out of their helical configuration. The nature of this locking element is such that it remains spring-like through repeated applications and severe shock loads. In fact, Uni-Torque Lock Nuts have a re-usability of five times or more.

The Uni-Torque Lock Nut starts freely on a bolt or stud like a common nut until the deflected thread portion is reached; then, it requires wrenching to final position anywhere on the mating part. The pronounced chamfer on the top of the nut makes it automatable by sight, feel or selective devices and makes it obvious that the end product is safe-guarded by a lock nut.

Uni-Torque Advantages

Lock on top allows nut to be threaded almost all the way on the bolt before wrenching is required.

Lock in middle allows locking effectiveness even when bolt does not protrude through top of nut.

Fully reusable many times without galling or seizing and without appreciable loss in locking torque.
